IMPROVED BRUSH-HOLDER.

@112 firlgehult nfsmt it in 111252 Wars gfintent at making part at thesame.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES B. CLARK, of the city of Buffalo, in thecounty of Erie,an d State of-New York, have invented a certain new anduseful Improvement in Scrubbing-Brush Holders; and I do hereby de\la.re

that the following is a full and exact description thereof, referencebeing had to theaocompanying draw. \gs,

making part of this specification, in whichfor inserting a woodenhandle, D.

Figure 1 is a vertical section of the brush-holder, showing the positionof the clamping-device.

Figure 2 is also a vertical plan, showing more fully the arrangement ofthe movable clamping-jaw and nut.

Figure 3 is a top viewbf the brush-holder.

Like letters refer to corresponding parts in all the figures.

My improyenient relates to a clamping-device provided with a longhandle, by which ordinary scrubbingbrushes can be held and operated bya, person standing The invention consists in constructing a movable jawconnected with and operated by a thumb-nut working on an inclined hollowshank, as hereafter shown and described. i

In the drawings, A represents a frame or casting, with afixed jaw, G,and hollow inclined screw-shank,F,

H is a movable jaw, working in a slot, as seen at L in fig. 2, said slotbeing east through the screw-shank F.

E is a thumb-nut provided with a flange, G, and which engages in aslotor recess, K, of the movable jaw, and is operated by means of thethumb-pieces I I, by which it is made to traverse the screw-shank inclamping or unclamping the brush. v

The operation of my improvement is obvious. The brush is placed with itsupper surface against the framefso that the jaw C will contact with oneside of the brush-stock, when the movable jaw H is pressed against theother side of the brush-stock, by rotating the thumb-nut E, whichtraverses the screw-shank F. The brush is readily released'by turningthe thumb-nut in the opposite direction. I

The movable clamping-jaw is prevented from being displaced by theportion of the wooden handle which is driven into the screw-shank.

By the peculiar construction of this brush-holder I am enabled todispense with drilling holes or using rivets, thereby greatly cheapeningits manufacture. I also produce a very light article, combining strengthand durability; and in eflioiency and ease of operation it is excelledby none. I

3 I do not claim a brush-stock or frame, in combination with aclamping-jaw, screw-shank, and thumb nut,.as I am aware that this hasalready beenpatented; but

Whatl claim as new, and desire to secure by Letters Patent, isl v aConnecting the thumb-nut E with the movable jaw H, liy means of theflange G and slot K, together with the mortise 'L in the screw-shank F,for the purpose specified.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
